Automotive Catalyst, On-board Diagnostic Monitoring
An automotive catalyst system health on-board monitor based on multi-dimensional detection metrics is presented in this work. The detection metrics are determined from the real-time measurements available in modern automo tive catalytic aftertreatment systems. Preliminary results based on experimental vehicle testing indicate that it is pos sible to perform accurate discrimination between catalysts of varying health using these metrics.
